Patent ES-373576-A1 (ES)
Title: Character recognition using mask integrating recognition logic
IPC: G06K9/64
Filed: 1969-11-15
Abstract: In a character form recognition device, the character form is shifted through a set of bistables in binarized form, a plurality of logical mask circuits pulsing respective counters on detection of respective patterns in the set of bi-stables, generation by the device of a signal indicating recognition of a character form being inhibited when the count in every counter does not reach a predetermined minimum value. The mask circuit outputs are passed to the counters only during a period following detection of a minimum character requirement in the set of bi-stables by a further mask circuit. This period corresponds to shifting through several columns of the character. Following this period, a train of clock pulses is fed to the counters in parallel, the first to overflow (count of 16) setting a respective stage of an output register and stopping the train. If no overflow is obtained within a first predetermined number of clock pulses, the operation ends. If overflow is obtained, a second predetermined number of clock pulses is applied to the counters, any further overflows setting the respective stages of the output register. Signals are produced indicating " at least one stage set," " no stage set," and " more than one stage set," respectively. Attainment of the first and second predetermined numbers of clock pulses is indicated when respective further counters fed with the pulses and preset to manually-selectable initial values reach predetermined counts. The initial value for the first further counter is 0, 1, 2, 3 or 4 and that for the second further counter is 0 or 1. The predetermined count for the first further counter is 12 and that for the second is selectively (a) 3, (b) 4, or (c) 3 or 4 according as the first further counter has or has not reached a count of at least 8. As modifications, a fixed number of clock pulses could be supplied to the main counters, the output register inputs being inhibited at the correct moment. Masks for different type faces of the same character may feed the same main counter via an OR gate.

Title: Device for the displacement of a solidification solid-liquid interface
IPC: C30B11/00
Filed: 1969-12-09
Abstract: Zone-melting is effected in a longitudinally elongated container (not shown) displaceable along its longitudinal axis between two ovens 12, 14 each provided with means for regulating the temperature of the material located within the oven at a predetermined value, respectively close to (oven 12) or above (oven 14) the point of change of phase, the oven 14 being located upstream of the oven 12 in the direction of movement of the container and being of higher heating power and thermal inertia than the oven 12. Oven 14 is displaceable along the said axis relative to oven 12 in response to a regulator means for maintaining constant the temperature gradient in the liquid phase in proximity to the solidliquid interface. As shown, oven 14 is displaced via rotatable screwed rods 17 controlled by gears 20 and motor 18. Both the ovens fit concentrically over the container, which is held at one end in a cooled heat-sink 16, itself attached to a screw-rod moving device 38, 40, 42. Temperature regulation may be effected using a thermocouple at each end of the container each differentially connected with a centrally-located thermocouple. The outputs from these are fed via electronic devices to control the power input to oven 12 and the position of oven 14. Regulation may be such that the maximum temperature in the melt is displaced away from the mid-plane of oven 14 towards oven 12. The ovens may be resistance heated, or may act through electric induction in the material being treated.
